here’s the link to my final settings for a different image in the laser tile thread. i think i used the same settings for this one as well (not at my home computer to check), but if not, it was very very close.
keep in mind that every photo is a little different. this picture and the one in the link above had a lot of contrast and dark areas, so ymmv depending on the image you’re starting with. i did a lot of photoshop work on both of them before burning as well.
you can see other people’s settings in that thread as well.
